19" Chassis

Dispersion is the phenomenon in which the phase velocity of a wave depends on its frequency (wavelength). It is sometimes called chromatic dispersion due to the wavelength dependency nature. This issue becomes prominent for higher data rate (shorter pulse width) as well as longer transmission distance.
